  • Use of the following within 1 month prior to screening/baseline: spironolactone, systemic steroids, systemic antibiotics, systemic treatment for acne vulgaris (other than oral retinoids which require a 6 month washout), systemic anti-inflammatory agents.
  • Use of oral isotretinoin (Accutane®) or oral retinoids within 6 months, or therapeutic vitamin A supplements greater than 10,000 units/day.
  • Use within 2 weeks prior to screening/baseline of the following: topical steroids, topical retinoids, topical acne treatments including over-the-counter preparations, topical anti-inflammatory agents, medicated cleansers, topical antibiotics.
